What feature distinguishes a compound crossbow from a traditional bow?

A compound crossbow is distinguished from a traditional bow primarily by its use of a trigger mechanism that holds the string in place. This feature allows the archer to draw the string back without having to maintain the draw weight manually; the trigger releases the string when the archer is ready to shoot. This mechanism provides greater ease of use, particularly for hunters who may need to hold the bow at full draw for extended periods while waiting for the right moment to shoot.

The design of a compound crossbow also contributes to its performance, allowing for more power and accuracy with less physical effort compared to traditional bows. Traditional bows, in contrast, rely on the archer's strength to hold the string drawn, which can be physically demanding. The trigger mechanism thus enhances the usability and effectiveness of the crossbow during hunting scenarios, making it a notable distinguishing feature.

Other elements associated with compound crossbows, like their weight or limb length, are not definitive in distinguishing them from traditional bows, as these characteristics can vary widely across different models of both types of bows.
